Ruby Versions

• Ruby 1.8.6 p114
• Ruby 1.9 trunk
• JRuby trunk
• Rubinius trunk ( at least runs source:examples/pingpong.rb ).

Most platforms run all specs and all the completed examples that don't have dependences. On many platforms other than 1.8.6, getting rake and/or autotest to run can be an issue, so the specs are run manually.
